INK CAPSULE.

Application filed March 2, 1922.

To all whom t may concern:

Be it known that I, BYRON B. GoLDsuiTH, a citizen of the United States, residing in N ew York, county and State of New York, have invented a certain Improvement in Ink Capsules, of which the following is a specification.

The many inconveniences and disadvantages of transporting and storing ink in liquid form are well recognized and various ways have been proposed for avoiding them by supplying apparatus whereby solid ink-producing material might be supplied to the consumer in such a way as to make it possible to produce a liquid ink by the mere addition of water when and where the ink was needed.

Dry ink powders variously compounded, and intended to be used by solution in water at or near the time and place of use, are well known in the art; but they are awkward to use and uncertain in effect, particularly in the hands of the average unskilled consumer.

The present invention relates to a novel means for the preparation of ink powder of any kind in a manner insuring the making of ink of exactly such proportions as are deemed best in a given case, without waste of powder and practically instantaneously. At the same time my improvement provides a very convenient package for shipping ink powder ready for instant use, which package perfectly protects the powder and keeps it in condition for insuring perfect results when used. The invention also has the advantage that it prevents accidental spilling on hands, clothing and so forth.

The principal or basic elements of the invention, which is claimed as novel per se, is a capsule, which may be given a variety of shapes, but is always characterized by the presence of a thin layer of ink powder (preferably uniformly distributed) which is confined between two protective layers of a permeable nature, although not necessarily in contact with both layers. The protective layers or either of them should be made of a permeable material such as cloth or the like.

These capsules may be combined with a supporting guiding element to form cartridges or with appropriate vessels used as ink stands, and both of these combinations form the subject matter of certain of the claims herein.

Certain embodiments of this invention are Serial No. 540,488.

illustrated by way of example in the accompanying drawings wherein Figures 1 and la are views partly in section and partly in perspective showing two forms of a circular capsule, Figure 2 is a sectional view of a simple form of cartridge with a removable capsule, Figure 3 is a sectional view of another form of cartridge provided with a number of capsules, Figure t shows a combined capsule and cartridge in section, Figure 5 is a partial sectional view of a modification of the device shown in Figure 4L, Figure 6 is a sectional view of an inkstand in which the device of Figure l is an element, Figure 7 is a view partly in elevation and partly in section showing another mode of applying the invention to an inkstand and Figure 8 is a view in section of a drumshaped capsule.

In the simplest form of capsule a thin layer of ink powder 10 is spread uniformly over a sheet or layer 11 or permeable material, preferably cloth or the like, and over this is placed a second similar layer 12, the whole being fastened together at the perimeter, as at 13.

As shown in Figure 1a, there may be a central permeable layer 14C, having thin layers of ink powder 15 and 16 on its opposite faces, confined in placed by outer permeable layers 17 and 18.

In use, water is simply poured through a capsule of this kind and ink is produced. No shaking or stirring is required and none of the powder can get loose to stain the fingers, clothing. etc.

In Figure 2 is shown a simple form of cart-ridge for putting to use the simple capsule of Figure 1 or 1a. This comprises a support and pouring tube 19, to one end of which the capsules can be applied so as to entirely close the opening, as shown at 20. The capsule may be applied to the tube 19 in any manner, as, for instance, by means of the threaded collar 21.

Where a larger quantity of ink or a more intense ink is to be made at once, a number of capsules 22 can be inserted at intervals in the main tube 19, being held apart in parallel relation by short interior friction sleeves 23, or otherwise.

Figure 4; shows a capsule and cartridge in one, the whole having a cylindrical form. Here an internal support of perforated material 24 may be used around which are successively wound the inner permeable layer and the outer layer 26, separated by the uniform layer 27 of ink powder'.

As shown in Figure 5a, a cylindrical capsule of this character may be made by first forming a fiat capsule like that in Figure l, but much larger, and rectangular in forni7 and then uniting the edges of the sheet to form the cylinder 28, by cementing or sewing.

This yform of capsule can be conveniently used as a component part of an inkvstand, as shown in Figure 6. Here the capsule, as 28, closed at one end as at 28a, is simply set on its closed end in a vessel 29, and water is poured into the latter outside ofthe cap suie. T is water percolates through the capsule forming ink within it, and the interior of the capsule is used as a dipping space for the pen.

lin Figure 7, the ink stand 30 has a threaded lilling orifice at 3l over which the capsule 2O is laid, being held in place by the removable funnel 32, screwed on over the orifice 3l. Water poured into the funnel will percolate through the capsule into the ink-stand and be converted into ink on the way.

. As shown in Figure 8, the permeable sides of the capsule need not necessarily both be in contact with the powder. Here the sides 33 and 34 are held apart by a rim 35, so as to form a small drum-shaped capsule, partly empty and partly filled with the powder 86.

Although l have used the term ink powder, l desire to be understood as also covering thereby particles of a larger size than actual powder as in some cases there is an advantage in using such larger' sizes with percolating spaces between them.

The examples described above are suflieient to make it clear that many changes may be made in the form and arrangement o-f the devices described without departing from the scope of the invention which is not limited to the details herein described and shown.

TWhat is claimedl. An ink capsule consisting of a hollow disc7 the opposite faces of which are made of materia-l permeable to liquid, and comminuted ink-producing material between the faces.

2. An inl; capsule comprising two or more retaining layers of material permeable to liquid but adapted to retain powder and sealed around their edges7 and one or more layers of init powder between said retaining layers.

3. [in ink capsule comprising two substantially parallel layers `of cloth sealed together around their edges and enclosingA al layer of comminuted ink-producing material.

d. n ink cap comprising two or more layers of material permeable to liquid sealed at their edges and enclosing a layer of ink powder shallow enough to permit ready passage of water.

5. in ink cartridge comprising a tube having closing means at one end7 said tube being formed of two or more retaining layers of material permeable to liquid but adapted to retain powder, and one or more layers of ink powder between said retaining layers.

6. An ink capsule as in claim 2 wherein the united layers are bent around as a whole with edges brought together to form a cylinder; in combination with a reinforcing per forated cylinder.

ln testimony whereof I have hereto set my hand on this 20th day of February, 1922.
